PATENT OFFICE l HUGH II. IIENDRIOXSON, or IJLKIIAR'I,V INDIANA, AssIGNOR 'ro Y'1:11a ADLARE oom- IANY, or CHICAGO, ILLINOIS, A CORPORATION or ILLINOIS` e CURTAIN ROLLER Applicationiled November 2, 1931. Serial No. 572,516.r

`The bracket 15is made Of sheet metal and This invention has todo withcurtain rollers, and is particularly concerned with rollers of the type commonly used for automobile window curtains.

One of the objectsof the invention is to provide, in a curtain roller assembly ofthe type described, improved means for facilitating the removal of the roller. Y

Another Object is to provide an' improved form of supporting bracket for -the roller.

Another object is to providean improved rangement and operationof-the novel brackl et, bung and trunnion parts.

In' order that the invention may be readily understood, one embodiment of the same is vpresentedherein, but it will of course be appreciated that the invention may be incorporated in other structurally modified forms coming equally within the scope of the appended claims. A

In the accompanying drawing:

Fig. 1 is a face view of an automobile window curtain assembly which "embodies the features of the invention; 1

Fig. 2 is a plan view of the assembly;

Fig. 3 is a fragmentary horizontal Section, taken on the line 3-.3 of Fig. 1; j

Fig. 4 is a vertical Section, taken on the line 4 4 of Fig. 3;

Fig. 5 is a side View ofthe bung before insertion in the end of the roller; and

Fig. 6 is a different side view of the bung before insertion.

The curtain assembly which is shown in the drawing includes a spring-wound roller 10; a curtain-11 onv the roller;y a hatten 12 at` the bottom ofthe curtain; ycords 13 at the sides of the window' in freely sliding engagement with eyelets in the ends of the batten; a -trunnion-gripping bracket `14 at oneend of the roller; anda trunnion-journaling bracket 15 at the other end of the roller.

of they strip 19 is apertured at 21 for the reception of attaching screws 22, while the other leg ofthe strip terminates in a rounded end'portion 23 which isprovided at its center with an Opening 24.` The cap 2O is positioned behind the end portion 23 of the strip 19, in cupped relationvto the Same, and the edges 25 of the cap arey turned over the edges of Vthe end portion 23, whereby to produce the above mentioned hollow headformation.

A disk-26 of fiber Or other suitable bear# ingmaterial is wedged-within the cap 20 between theflatter and the end portion 23 of the strip 19 and is provided, at its center, with a'bearing aperture 27, of smaller size Vthan the opening 24, for the reception of the outer end of the trunnion 17. The end polition 23l is provided, about the openingr24, with an outwardly projecting annular rib 28 for rotatable engagement .witha disk 29 on the iend of the bung 18. The end portion 23l is also provided, as a result of the annular rib formation 28, with an inwardly projecting'` edge 30 for fixed engagement with the bearing disk 26.

The cap 2O is provided at its center with a Smalll hole 31 in axial alingnment with the `bearing aperture 27 in the disk 26. The purpose of the hole 31 is to permit a small pointed tool to be inserted vthrough the same into engagement with the end of the trunnion 17, whereby to force the trunnion axially back into theend of the roller in order to dislodge the trunnion from thebracket.

Thebunk 18 is made for the most part of sheet metal, and includes, in addition to the Vpreviously mentioned end disk 29, a U-shaped ends of the U-shaped strip 32. The trunnion 17 is journaled near its inner end in a bearing aperture 36 in the center of the disk 33 and is journaled near its outer end in a bearing aperture 37 in the center of the cross web 38 of the strip 32. The trunnion also passes through an aperture 39 in the center of the end disk 29, but the last mentioned aperture is somewhat larger than thetrunnion and the Amaterial. of the cross web 38 is sleeved through such aperture and spun out against the outer face of the disk at 40, thereby providing an extended bearing surface for the trunnion at that point.

The bung 18 is telescoped within the end of the roller 10, with the disk 29 on the bung in abutmnet withthe end of the roller, and is held within the roller by the provision of indentations 41 in the sides of the same which are forced into apertures 42vin the sides of the bung.

The trunnion 17 is characterized by an enlargement 43 intermediate its ends, which enlargement abuts with the inner face of the cross web 38 of the'U-shaped strip 32 and gn limits'the outward movement of the trunnion. A coil spring 44 is mounted on the trunnion between the enlargement'43 and the disk 33, and serves to normally maintain the trunnion in its fully projected position.

The bracket 14 at the other end of the roller may be, and preferably is, constructed like the bracket 15, but there is no occasion to have in the bracket k14 any opening corresponding toA the aperture 31 in the back of the head portion of the bracket 15. The bracket 14is preferably provided with an elongated slot iny order to receive and nonrotatably engagepwith the ordinarily flattened end of a spring-.wound trunnion 45 in that end of the roller. Y

It will be noted in the drawing that the attaching portions of the brackets 14 and 15 are directed inwardly toward each other behind the roller. This arrangement conceals the attaching portions from sight and also permits the brackets to be attached to a short window frame member 46 which may be of even less length than the roller. l

The above described curtain roller assembly cannot be removed inthe ordinary well known way, but requires specialmanipulation7 thereby preventing tampering and theft. In order to remove the roller, one

`must know of thepresence and purpose of the small opening 31in the back of the bracket 15.V With this knowledge, it is a simple matter for anyone to insert a suitable tool, such as the end of a punch, a nail7 or a wire, in the hole and force the outwardly spring-pressed trunnion far enough inwardly .to clear the bracket. r
